Application filed August 27,1923. 4'Serial No, 659,620.

To all whom t may concern.' f

Be it known that I, JOHN BEATHAM, a citizen of the United States, residing at Rio Vista, in the county of Solano and State of California, have invented certain new'and useful improvements in Liquid-Fuel Burners, of which the following is a specification7 reference being had to the accompanying drawings.

This invention relates to liquid'v fuel burners. j f

An important object of the invention is to provide a simple and inexpensive fuel burner of this character having means whereby the liquid fuel isconverted to a gaseous'one prior to the burning` thereof.

A further object of the invention is to provide a device of this character composed of unitary castings, with the exception of such necessary accessories as feed pipes and the like. j

A still further object of the invention is to provide a device of this character which will operate evenly when the flow of fuel thereto is comparatively low.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration I have shown a preferredembodiment of my invention and wherein i Figure y1 is a perspective view of the burner constructed in accordance with my invention;

Figure 2 is a side elevation partially in section thereof;

Figure 3 is a section on the line 3 3 of Figure 2; and

Figure a is a detailed sectional view showing the air inlet.

Referring now more particularly to the drawings, thenumeral 10 indicates a lunitary casting formed to provide a substan-` tially cylindrical casing 11, the ends of which are closed by end plates 12 serving as a support for the burner. TheV casing 11 is subdivided to form main and auxiliary compartments 13 and 14, the main com partment comprising the body or gas chamber of the burner and the auxiliary compartment being formed in the peripheral wall of the main compartment and being partially within and partially without the main compartment. The auxiliary compartment is provided adjacent one end wall 12 ywith an opening 15 communicating with the atmosphere and is provided in its upper wall formed in the chamber 13,

`with afplurality of spaced openings 16, placeres.,

ing the compartments 13 and 14 in communication between vthe edges ofthe wall of the compartment 14 and points represented by theintersection of a horizontal plane, designated at l?, withthe walls'of'the 'compart-` ment 13, this plane passing through the approximate' axis of the compartment 14. The walls of the compartment v13 are provided with vertically extending llongitudinallyspaced slots 17. It will be noted that above the upper edges of the slots 17 a pocket is the l'purpose of which willV presently appear. f. f f

The end walls 'rorfplates are".provided U with aligned openings 18 through which'fex- A tends a feed pipe 19,' one end of which is adapted for connection with the supply pipe and the opposite end of which enters an elbow 2O secured to the corresponding end plate and to the end wall in alignment with the end of the compartment 11i, the end plate being that at the end 4of the casing 10 next adjacent the opening 15 of the compartment 111. The end of the supply pipe 18 is directed throughan opening 21 formed in this end plate and into the compartment 14, terminating immediately above the opening 15 of the compartment.

In the operationA of the device, assuming sufiicient heat hasbeen applied to the fuel pipe 13, to converty fuel passing therethrough into a gaseous vapor, this vapor discharging from the end ofthe supply pipe is mixed with air enteringat the opening 15. Being heated, the gas thus formed passes upwardly through the openings 16 of the wall of the compartment 14.v and into the compartment 13, where still rising it collects in the poclret above Vthe upper ends of the slots 17. If the burner be horizontally positioned, as intended, this gas will escape from these pockets through the upper ends of the openings to bey burned, the amount of gas passingl through each ofthe openings being approximately equal and accordingly a uniform ,y

but likewise to the flame passing from the n of, these openings providing a means forV suspending a core for use in forming a chamber 13 and being duringV operation closed by removable plugs 25.

It will be obvious from the foregoing that.

burner constructed in accordance With my inventionmay be very cheaply produced and at the same time will afford a structure use of liquidhydrocarbons as fuel.` It will furthermore vbe obvious that the structure thereof is capable ofl some change and modification VWithout materially departing from thespirit of my invention and 1 accordingly do not limit myself to such specific structure,

except as hereinafter claimed.

ron vviding a uniform flame and admitting of the 'weaves I claim c i ln a hydrocarbon burner, a casing formed to provide substantially cylindrical main and auxiliary compartments, said auxiliary conlpartment ybeing formed in the lower Wall Y of the main compartment and .being disposed partially within and partially Without the main compartment, openings formed in the Wall of the auxiliary compartment connecting the compartments, an opening in the auxiliary compartment adjacent one end thereof communicatingivith the air, and the end Wall of the main compartment being provided With an opening affording access thereto, a removable closure for said opening, and vertical slots formed in the Wal] of said main compartment having their lower ends disposed immediately adjacent the Wall of the auxiliary com artment and their upper ends spaced therei in the upper end of the main compartmentl a gas pocket. V

In testimony whereof I hereunto affix my signature.

JOHN BEATHAM.
